Should I focus on teaching him the basics of personal finance, like saving and budgeting, or is there a way to introduce him to more advanced concepts like market analysis? 

I fix n flip and I always add the cost of paying an agent in my budget.  

I ultimately obtained a variance to build 12 townhomes and 18 condos reliant on my hardship case and by agreeing to take responsibility for replacing the retaining wall in a re-designed terrace approach that stepped the wall back from the most immediate neighbors which was a rounding error once applied to the overall project budget.

I have had no luck trying to propose seller financing through realtors for on market listings.Bottom line, either spend some time and/or money marketing direct to seller or networking with investors that have been around for awhile.

Things to consider1) Number of bedrooms / bathrooms / space for your tenants you can get for the $ you spend.

That is just a one off report so before you spend a buck fiddy, it is a good idea to visit a couple TK operators in person first.

Quote from @Evan Polaski: @Jay Hinrichs, while I wasn't going to call them MLM, I did attend an Armando Montelongo (A&E's Flip this House from mid 2000's) seminar at a hotel conference room in 2007 or 08, which was the free funnel to spend $1,500 for a three day seminar or $25,000 for an in-person mentorship.I have seen similar promoted with Christina and Tarrek from Flip or Flop more recently.I didn't start realizing how profitable education can be until the last 5 or so years.  

On an annual basis, the administration is mostly meeting minutes, resolutions, and annual filing of your 990, most of which can be outsourced depending on your budget.

Eventually we upped the budget to get something we would absolutely love even if it was slightly cash flow negative.

They got fundamentally sound real estate, with matching debt (10+ yr fixed rate) and budgets with the intent to hold nearly forever.
